CAUSE: Firmware update required.

SOLUTION: As an immediate workaround, please set the [Image Stabilization Setting] to other than [Black Priority] then turn OFF/ON the main power switch.
There is firmware to prevent the jam code from occurring. Please access the Download Selector or One-Stop Product Support, then download and install special firmware version GC1-65.

Well, the problem is gone... Today I changed the PRCB board from an other machine, and the problem is gone.
Changed back the original, for verifying the problem, and the 99-01 is back. So it is obvious, that the PRCB is the problem, somehow it has gone wrong in the process.
I was very embarassed, because I swore we changed that board the first place. Well, looks like we didn't. Somehow I goofed...

Thank you all again for you time and the suggestions!
